How do eukaryotic ribosomes prevent false starts at inappropriate parts of the mRNA?
A) There is a consensus sequence, called the Kozak sequence, surrounding the start codon in eukaryotes.
B) The Shine-Dalgarno sequence positions the ribosome properly, just as in prokaryotes.
C) Only one start codon ever appears in eukaryotic mRNA, so false starts are not a problem.
D) Nothing; false starts are quite common in eukaryotic translation.
